Hey! Look what I found online.
In general, it makes the angiosperms more efficient in pollination and, therefore, in producing seeds. Most angiosperms have perfect or bisexual flowers, that is, both the male and female reproductive organs are borne on the same flower while these are separated in the gymnosperms. In the conifers which are gymnosperms, thousands of pollen grains will be needed to pollinate one female. The pollens are carried by the wind and having one pollen land exactly on the stamen is quite an impossibility.
<span>Many angiosperms have colorful petals. This attracts the insects and birds. As they move from one flower to another, they deposit the pollens on the stigma of another flower. The nectar that angiospermous flowers produce and the aroma emitted play the same role.</span>
1.) It's best to have two pair of eyes for an experiment. Meaning one person to watch the chemicals while you're writing things down - especially if they're dangerous if mixed together. Basically it's best to take turns!
2.) They may have different results than you if you're in a lab - and it's always best to work together to get the job done! You can get the job done faster and more effectively if you work together! (:
I hope all is well, and you pass! Good luck, rockstar!
